Description

This one's been in my inbox for a while. People use "for x reason" instead of "for the x reason" or "for reasons".
This linter fixes all the common ones I could find.

I also converted WordSet into a real Rust collection that works with .collect() by implementing FromIterator thanks to Google Search's AI giving me really good tips on how to best use WordSet with a transformed collection rather than its usual static array of static &str.

This linter does not convert existing callsites of WordSet.

How Has This Been Tested?
